The army commander said terrorist groups operating in the region are not capable of posing any threat to Iran.
"We do not regard terrorist and takfiri groups as a threat," Lieutenant General Ahmad Reza Pourdastan said, adding, "The units deployed at the borders possess great capabilities and the ground troops of the Armed Forces are ready to lend a hand to the Islamic Revolution Guards Corps (to deal with such groups) if need be."
A takfiri is a Muslim who accuses followers of other faiths and some Islamic sects of being unbelievers.
He made the remarks in a press conference on Sunday ahead of the National Armed Forces Day, which is celebrated annually on April 18, ISNA reported.
"Due to the presence of non-regional forces, we were involved in an asymmetrical atmosphere over the past years," Pourdastan said, adding, "The enemy's defeats in recent years have made it change its war tactics and turn to a proxy war."
"(Now that) Boko Haram and Daesh (the Arabic acronym for IS, standing for the Islamic State of Iraq and the Levant) militants are committing crimes on behalf of the United States. We are to ready ourselves for (fighting in) the conditions of proxy wars."
"We are monitoring threats and practicing the tactics of asymmetrical warfare."
He referred to the Saudi strikes on Yemen, predicting that the resistance mounted by the "brave" Yemeni nation will bring the Saudi army to its knees.
"As a military man, I advise the Saudi army to cease its aggression, or it will definitely suffer a defeat," Pourdastan said, adding while the Saudi army has not yet been put to the real test in this war, it has already shown signs of defeat.
